Assembly - Polaris Engines
The cylinder mounting studs on Polaris engines are used to secure crankcase halves along with the crankcase
bolts. Do not allow crankcase sealer to cure before torquing base nuts or assembling the top end Be sure all
top end parts are clean, inspected, and ready for assembly priorto assembling engine lower end. Improper crank
shaft main bearing clearance may result if sealer dries, causing premature engine wear. Be sure to follow the
Crankcase Assembly procedure below when assembling crankcases
1 . Clean crankshaft and lubricate with Polaris
Premium 2 Cycle Oil.
2 . If new outer main bearings are being installed, heat
new bearings on a hot plate.
Wear protective gloves to avoid burns when installing
bearings.
3 . Install inner bearing on PTO end. Install spacer and
outer bearing. Be sure bearings are fully seated. If
necessary, tap bearing lightly on inner race only
until fully seated.
Do not drive on outer race or bearing damage may occur.
